To all whom 1i-may conce/m: f

Be it known that l, IRA L. SCOTT, a citizen of the United States, residing at Fort Colv lins, inthe county of Larimer and State of Colorado, have invented certain new and useful Improvements in Two-Way Motor- Plows; and l do declare the following to be a full, clear, .and exact description of the invention, such as willenable others skilled in the art to which it appertains to 'j Y 2 ofthe drawings.

make vand use the same.

This invention relates to. new and useful improvements in plows of that class having a'motor driven frame providedwith two sets. of plows facing eachhother'and movf thereby is adapted to be mounted any type able into and outiof their yoperative-positions, so that the machine may be driven i leither forwardly or backwardly for plowing ttl ` to provide means for transversely adjustingsuccessive furrows without turning the machine entirely around.

rlhe primary object of my invention is to provide a simple, practical and efficient :tractor plow having a plow carrying member so mounted that a more ydirect pull upon thelplows is obtainable than with any of the tractors in use at the present day..

i Another object of this invention is to provide a device of this character which is so' arranged that thetraction wheel` and steering members will travel on the ,solid ground,

while the plows are in operation,

A; still further object of theginvciiton' is and varying the number of plows carried by the balanced supplemental frame, and also making' the plows easily removable therefrom;

A. further object of the invention is tol provide a device of this character which is simple and durable in construction, inexpensive to manufacture, and one which will be very efficient in operation.

g `With these and numerous otherobjects in view, my invention consists of the novel features of` construction, combination and arrangement of parts which will be hereinafter referred to and more particularly pointed out in the specification and claims.

1 ln' the accompanying drawings:

j Figure 1 is a side .elevatilonlof my im-f proved plow; .and lFig. 2 'is a top pla-n view, of the same.`

In describing my invention, l shall refer to. the drawings in which similar-reference Eli characters designate vcorresponding parts throughout'the several'views, and in which the numeral 1 ldesignates a main frame, havl ing longitudinally extending side bars 2 and ends 3. Mounted between the side bars 2 of the frame 1 is a longitudinally extending bar 4, which projectsfroin one end of the ccf frame to the other. The side bars and ends of this frame, as well as the intermediate longitudinally extending bar 4, are secured' at their ends by means of plates 5, which are riveted thereto as clearly shown in Eig.

of engine ofjstanda'rd make, together with a means i connected therewith for driving a transversely extending central shaft 6 which is mounted thereon in bearings on the opposite side bars of the,main frame. A"

tractor wheel 7 'is mounted on said shaft. '.l `he tractor wheel 7 is provided onits periphery with a plurality'of transversely extending 'l' iron cross bars which enable the same to readily gri into the ground.

rllhe tractor wheel37 forms a support for one side of the main frame l, and the other side thereotnv is supported by a pair of steering-and supporting wheels 8 which are disposed adjacent the ends of the same, and are mounted on axles 9, which project inwardly and upwardly through the oppositecorners Lof the frame, and have a large beveled gear 10 on the upper end of the same. Projecting longitudinally with the frame 1,. and spaced above the same, in bearings 11, which are secured to the Ibar 4, is a steering shaft '12 which is operated by a wheel 13, and has on its oppositeends beveled pinions which vare adapted to meshv with the, beveled gears 10 on the ends .0f the axles of the steering wheels. By lthis means it will be obvious that upon rotation of the wheel 13, the shaft 12 will be turned, and this motion will be transmitted to the steering supporting Y wheels 8, .whereby the machine may be turned when' desired.

The plows of this device are supported by means of a supplemental longitudinally extending balanced frame 15, which is pivotally mounted 4intermediate its ends on a pair of stub axlesrl which project inwardly lll-0 from the side `of the bar 4, and the adjacent side bar lQ-'beneath the axle or supporting shaft 6 of the tractor .wheel 7. This frame,

` 15 substantially rectangular shape,

comprising parallel side bars 17, and ends 18. The supplemental frame 15 is provided a Supportr kand securing means for the f plows 21..

vtending bars may Ibe adjacent its ends 182'withapair of cross' -bars 19, which 'are disposed adjacent the opposite ends of the tractor wheel whenthe y frame is inposition, and which are adapted 4to form-v supports for longitudinally extendlng bars ,20 which extend from said cross bars to the ends, 18 of the frame, andform -The Vlongitudinally extending bars 20 are adapted to `be transversely adjusted along the ends `18,"and the cross bars 19 between 'the sides 17` of the'supplemental frame, by any desiredjmeans, preferably by means of bolts 22 projecting through the ends of. the longitudinally extending bars, and openings 24 adapted for alinement therewith in the cross bars 19'- and the ends 18.

operative position. These plows 21 -are faceso ingeach other, so thatit will be obvious that when the machine is running in one direction, the plows at the rear ot the supple` mental frame when brought into, contact With'the ground, maybe readily placed in operation. Thus l'when the machine has reached one end of the field, itis not necessary to A'turn vthe same entirely around, but the supplemental frame .is merelyv shifted, whereupon the plows 'at the-opposite end of the same are brought into operation, and the ones, `at itsfrontend removed from the ground, whereby it may'proceed back across .the field. This supplemental frame is so mountedthat onlythe plows-at one end of the same may be in operation at the same The plows 21 are` suspended from the bars 20 by supporting members 25, and additionally supported by braces 26. It Will be obvious from the drawings that the' lows which are shown two in number at eac end ofthe supplemental frame, are spaced one in front of the other, andthe plow nearest the tractor wheel is so positioned, however, that it will always be 1n direct -alinement with j the adjacent plow. By this positioning, the

machine will always plowI evenly when in operation. Anytype of engine may be used A comprising in combination a to 'drivel this plow, and the same maybe mounted on the main frame adjacent one side of the tractor wheel, so that it may be easily connected with the axle 6 of the same.

This axle extends'across the top of the main frame, and is mounted in lbearings 27 disposed on the side bars 2, and the interme- -diate bar 4.

l -From the foregoing description of the conmounted in said frame, a supplemental balancedframe pivoted in the main frame be-A neath the axle of the tractor wheel and surrounding vsaid Wheel, and earth Working elements on the ends of said supplemental frame disposed in the line of travel of the tractor wheel.
